To 77 (P71 0221. it may concern.

lie it known that l. Joux F. 11 ULE, a'eitizen of the United States. residingin Jamaica, borough of Queens, in the county of (Queens and State of New York, have in vented certain new and useful Improvements in 'lypeJV -iting Machines, of which the following :ISPfl'lfiCfzltlOll.

My invention relates to means for indicating and gaging the width of the bottom margin of a work-sheet. In devices of this character it has usually been necessary, in .order to set the gage or indicating device for a. predetermined margin on the work sheet, to first mark or indicate on the worksheet the width of margin desired and then run the sheet through the machine to bring such mark to the printing point, and then set the indicating device or gage accord iugly. Such process has time a worksheet of different length is used.

An object of the present invention is to eliminate this indirect and time-consuming method of setting the gage, and to enable the indicator or gage to beadjusted to a work-sheet prior to its insertion in the machine, whereby the indicator may be readily and accurately set for worksheets of different lengths, and also gaged for a bottom margin of any desired width without any preliminary testing, experimenting or running the work-sheet over the platen.

A support or standard may be removably attached to. the paper shelf in rear of the platen, and provided with a ledge or other indicating means. for a worksheet. A can rier in the form of a clamp, slidably mounted on the standard, has pivoted thereto an arm carrying a gage or indicator, which, when said'arni is swung upward, may be adjusted to a Work-sheet placed on said ledge. The swinging arm is of such length that when again swungdownward after bemg adjusted to a work-sheet, it is automatically brought'to ndicating stop for the work-sheet whenthe latter has beenrun through the machine so that its bottom edge is at or near the printin The indicating gage is vary the effective length of said arm, and thereby indicate margins of different widths, a scale beihg provided on the gage enabling the operative to set the same'for a margin to be repeated each 2 at the rear of the proper position to form an I adjustable to Patented Diary a, mic. Serial No. 790,823.

A rotary platen 1 having ends 2 connected by platen, said shelf co1nprising extensions 4 beneath the platen and extending to within a short distance of the printing line. Types 5 strike against the front face of the platen.

In the Underwood typewriting machine the upper edge of the' paper shelf 3 is usually curled to form a head 0, which, together with a brace rod 7 below said bead, is utilized as a holding means for a remov able standard 8 on which a margin indicator is mounted. The standard as shown, may comprise a single upper end of the standard to allel rods 9. Tl

d 6 and the brace rod 7 said member 10 having an intermediate for a margin indicator or gage 13 adjustably I mounted 11'}. a swinging arm 14 pivoted to the clamp 12. .The'clamp 12 may be made from a piece of spring sheet metal bent to is mounted in a frame a paper shelf form a front plate 15 and a rear plate 16 united by a section provided with an open-- ing 17 through which the rods ,9 extend.

" The lower end of the plate 16 has a for- 1 rod offset at one end andcbent to form a form an indicating or positionlng means for j clamp v wardly extended offset 18 formed with an opening tend. Normally the front and rear portions 15 and 16 of the clamp are sprung apart so as to bind on the rods 9,.and thereby frictionally hold the clamp in any position of adjustment. By gripping-the clamp be tween the thumb and finger, the rear plate 16 may be swung forward to the Fig. 6 position, and the clamp thereby released to permit adjustment on the standard 8.

The swinging arm 11 may be formed of a on liolder 23 in'which the indicating gage ,1? as adjustably supported. 1 A ledge 24 on which a worksheet 25 -maybe sup ported,

asindicated by dotted lines-in Fig. 1, whe ithe slide 12 is being adjusted, is

preferably located near the lowerend of the standard 3, and as shown, isin the form of a tonguj stamped out of the support; 10 and bent foiWa-rd. [It is to be understoodthat the primary function of the l edge"24 is to one end edge of a work-sheet while the slide 12 is being, adjusted to bring the gage 13 to i the other end of said sheet, andtherefore an indicating-mark or other means to indi- I cate a definite position for thelower end of the place of the ledge 2 1-. c j

The distance between the upper andlowen the worksheet might in someinstances take positions of the gage13 for any given position ofthe support 12 (assuming the gage line position,

13.130 beat its innermost positionof adjust ment along the arm 14) is substantially "equal to the distance from the lower gage or support 24 to the printing line on the platen. The purpose ofthis relationlof parts will more fully appear, in connection with the description of the methodvof operation and use, which is substantially as follows:

The gage 13 being moved inwardly along the arm 14 to the position shown and said arm 14 being swung the work-sheet with its lower edge on the ledge 21 and the clamp 12 is adjusted to bring the gage 13'to u to dotted- 2% the upper edge of the work-sheet, as shown,

19 through which the rods 9 6X1 yibldingly holds the arm 14'both osition, shown in broken linesm we end of the arm'l l is a spring short gage arm tobe used.

in Fig. 1, I

is placed.

in dotted lines in Fig. 1. If, now, the worksheet is placed in the machine and the gage 13 swung down to the full-line position, Fig. 1, and the work-sheet fed forwardly in the usual manner by rotating the platen, it will be found that the leading edge is brought up to the gage 13, when the bottom edge of the work-sheet is at or near the printing line.

Two methods of adjusting the gage 13 for any predetermined width of bottom margin on the work-sheet, may be used. First, the

work-sheet may be positioned as, shown in dotted lines, and the gage 1.3 set, as already described. The gage 13 is then drawn out wardly a distance equal to the desired width of margin on the work-sheet, as for example, one inch, the distance being indicated by a scale 26 on the arm of the gage 13. The

work-sheet may now be placed in the machine and the arm '11 swung downwardly,

bringing the gage 13 into such position that,

when the leading edge of the work-sheet reaches the gage during the operation of the machine, the printing line will be an inch from the bottom margin of the sheet; The

second method of usingthe indicator con-* sists in first drawing the" gage 13 outwardly along the arm 1 11a distance equal to half the desired width of margin. For example, if; an inch marg n is desired, the'gage 13 1s;

drawn out a haltineh, which is indicated out the scale. Thework-sheet is then placed on the ledge 24 and the clamp 12 adjusted to bring the gage 13 to the upper edge of the work-sheet. The latter being remoi'edfroln the ledge, the arm 1-,: is swung down, and is thus-brought intothe same indicating position as in the first described method of adjustment. This second method has the advantage that a wider range of adjustment is permitted with a given range of movement.

a. comparatively,

of the gage arm, permitting Also, the gage may beadjusted on the swinging arm before the work-sheet istouched. The scale 26 may,if desired, be graduated to line-space distances. For, example, the successive markings may be single line-space distances apart; the number of graduations on the scale appearing below the support 23 will thus indicate the width of the bottom margin asmeasured in double line-space distances.

1 Variations may scope of the invention, and portions of the improvements may be used without others.

Having thus described my invention, I
